Title: Denitriding method and denitriding and decarburizing method for molten metal
Inventor: YAMAGUCHI KIMIHARU
IPC: C21C7/076
Filed: 1995-03-03
Abstract: PURPOSE: To provide high-quality products by blowing an oxidizing gas to a coating slag surface to an extent of not coming into direct contact with molten metal. CONSTITUTION: The molten metal (molten steel) is charged into a refining vessel having a gas top blowing function. The surface of this molten steel is coated with the slag consisting essentially of CO and Al2 O3 at >=15kg per 1t thereof. The oxidizing gas contg. O2 and/or H2 O is thereafter blown to the slag surface to the extent of not coming into direct contact with the molten steel. The molten steel is thus subjected to a denitriding treatment. The concn. of Al in the molten metal is maintained at >=0.5% in at least one period during the denitriding treatment. Stirring by the bottom blowing gas is used in combination. The molten steel is subjected to a decarburizing treatment by blowing the oxidizing gas into the molten steel after the denitriding treatment. A flux contg. iron oxide is added to the molten steel for the denitriding treatment.  As a result, the denitriding down to an extremely low nitrogen concn. level can be executed.

Abstract: PURPOSE:To freely change a lengthwise size of a packing bag by changing a length of a leg member provided on a lower face of a main body according to a working amount of a feed means for feeding a bag material downward. CONSTITUTION:A bag material A'' formed by a vertical sealer 23 is fed downward by a pair of pull-down rollers 31a, 31b of a feeder 30. A receiver 71 is lowered by a receiver motor 80 according to the fed amount so that it is positioned at a height approximately in contact with a lower end of the hung bag material A''. On the other hand, if a packing bag is so long that a sufficient packing space cannot be reserved from a lateral sealer 50 even if the receiver 71 is lowered to a position in contact with an installing face, a control unit rotates a leg 93 by a leg driving motor to have a main body 2 raised from the installing face. Since a packing apparatus 1 suppresses an occupation space in a working site, it is normally placed at the lowest with respect to the installing face. Therefore a length of a packing bag can be set without originally increasing a height of the packing apparatus 1.
